남성도 갱년기를 겪는다. 중년 여성의 전유물로 여겨졌던 갱년기가 남성에게도 나타나는 것이다. 40세 이후 남성의 신체기능 저하는 최근까지 자연적인 노화현상으로 치부됐다. 그러나 평균수명의 연장과 의학의 발달 등으로 건강한 노년 생활에 대한 욕구가 커지면서 남성의 갱년기 증상이 발견되기 시작했다. 특히 20대에 최고조로 증가하는 남성 호르몬(테스토스테론)이 점차 줄어들다가 40~55세 사이에 급격히 감소하면서 여러 가지 신체적, 정신적, 심리적 변화가 나타난다. 남성호르몬 감소의 첫 번째 징후는 부부관계에 관심이 없어지고, 좀 더 진행되면 만성피로를 느끼고 얼굴이 달아오르거나 식은 땀을 흘리며 손발이 저리기도 하다. 그리고 감정이 잘 조절되지 않아 사소한 일에도 짜증을 내게 되는데, 남성 호르몬 부족 때문에 나타나는 이러한 증상들을‘남성 갱년기’라 한다. 이번 호에서는 서울아산병원 비뇨기과 안태영 교수와 성의학클리닉 연구소 강동우 전문의의 도움으로 남성 갱년기에 관해 자세히 알아본다.

투구운동은 견관절에 반복적인 압박력 및 신장력을 가하게 되며， 이는 견관절의 정적 안정력의 약화를 유발하게 된다. 초기의 경도의 불안정성은 근육 동 동적 안정력의 작용으로 안정적인 운동상태를 유지할 수 있으나， 반복적인 운동이 지속될 경우 근육이 피로해 져서 동적 안정력의 보상작용을 통한 안정성을 얻을 수 없게 된다. 이는 일차적으로 견관절의 불안정성을 유발할 뿐만 아니라， 이차적으로 견봉하충돌증후 및 내적충돌증후 등의 증상을 나타내기도 한다. 과 투구로 인한 대부분의 운동손상은 보존적 치료로 좋은 결과를 볼 수 있으며， 이는 일차적으로 투구를 중지하여 관절을 안정시키며 진통 소염제나 물리치료 등을 통한 항 염증치료， 그리고 회전건개 및 견갑골주위근육의 강화운동 둥의 단계로 진행된다. 적절한 보존적 치료에도 불구하고 증상이 지속될 경우 정확한 진단에 근거한 수술적 치료 및 조절된 재활운동 프로그램을 통해 조기 운동 복귀를 기대할 수 있다.

Purpose: Three-dimensional (3D) displays are very useful in many fields, but induce physical discomforts in some people. This study is to assess symptom type and severity of asthenopia with their habitual distance corrective spectacle (HDCS) and their binocular vision corrective spectacle lenses (BVCSL) in people who feel physical discomforts. Methods: 35 adult subjects (ages $32.2{\pm}4.4$ yrs) were pre-screened out of 98 individuals to have the highest symptom/asthenopia scores following 65 minutes of 3D television viewing with HDCS. These 35 individuals were then retested symptom/asthenopia scores during they watched 3D television for 65 minutes at a distance of 2.7 m with wearing BVCSL of horizontal, vertical or base down yoked prisms. A 4-point symptom-rating scale questionnaire (0=no symptom and 3=severe) was used to assess 11 symptoms (e.g., blur, diplopia, etc.) related to visual fatigue/visual discomfort. Distance and near lateral phoria were measured using Howell phoria card and vertical phoria were measured using Maddox rod. Symptoms induced by watching 3D TV were compared between wearing HDCS and BVCSL. Results: Asthenopia in watching 3D TV with wearing BVCS was significantly lower than wearing HDCS at 5, 25, 45, and 65 minutes (all p < 0.001, paired t-tests). In only refractive error power correction power group, all asthenopia was not significantly different between HDCS and BVCSL (all $p{\geq}0.05$, paired t-tests). In prism correction groups for binocular imbalance, symptoms of asthenopia, however, was significantly lower for when wearing BVCSL than when wearing HDCS (all p < 0.05). Conclusions: Correction of phoria/vergence-based binocular vision imbalance can reduce asthenopia during 3D television viewing. An individual with binocular vision imbalance need corrected/compensated glasses with appropriate prisms prior to prolonged viewing of 3D television displays to reduce asthenopia/visual fatigue.

Purpose: The purpose of this case study is to prescribe a prismatic correction in uncommon case of cyclovertical heterophoria. Methods: The prescribed prism was used to balance the vertical vergence break values by the binocular vision evaluation such as phoria, vergence, accommodative function and the others. Results: Although asymptomatic lateral phoria was changed, the vertical prismatic correction improved the symptoms such as eyestrain, headaches, diplopia and others. And cyclophoria was disappeared by prismatic correction. Conclusions: The prismatic correction for this case was useful for alleviating symptoms of cyclovertical deviations.

Objectives : This study aims to identify various psychiatric symptoms and psychosomatic symptoms caused by COVID-19 infection and investigate their long-term impact. Methods : A systematic literature review was conducted, selecting papers from domestic and international databases using keywords such as "COVID-19" and "psychosomatic." A total of 16 papers, including those using structured measurement tools for psychosomatic symptoms, were included in the final analysis. Results : Psychiatric symptoms such as anxiety, depression, and somatic symptoms have been reported in acute COVID-19 infection, while long-term post-COVID symptoms include chest pain and fatigue. The frequency of long-term psychosomatic symptoms has been estimated to be 10%-20%. Factors contributing to these symptoms include psychological and social stress related to infectious diseases, gender, elderly age, a history of psychiatric disorders, and comorbid mental illnesses. It is suggested that systemic inflammation, autoimmune responses, and dysregulation of the autonomic nervous system may be involved. Conclusions : Psychosomatic symptoms arising after COVID-19 infection have a negative impact on quality of life and psychosocial functioning. Understanding and addressing psychiatric aspects are crucial for symptom prevention and treatment.

The purpose of this study was to examine the effect that preferred music listening had on police officers' occupational stress and fatigue. The musical intervention took place over a total of six sessions from October 11 to October 19, 2016. At each session, the experimental group (n = 19) received 20 minutes of music listening with individually customized playlists that were compiled based on their preferred music list. The control group (n = 21) simply took a break from work for 20 minutes. Every participant checked his or her occupational stress and fatigue level before and after the experiment using the Occupational Stress Inventory and Subjective Symptoms of Fatigue Test. The data were then analyzed by the SPSS 22.0 statistics program. To examine the homogeneity and pretest-posttest results between groups, an independent t test was conducted, and a paired t test was used to examine the pretest-posttest results within groups. The results confirmed all hypotheses. Findings support that the use of preferred music listening is an effective way to help police officers to control their occupational stress and fatigue. This study used a convenience sample and has limited generalizability. Future research should explore interactive approaches in music therapy as well as receptive music listening for alleviating police officers' occupational stress and fatigue.

최근 들어, 건강에 대한 관심이 고조됨에 따라 일상생활에서 식품을 통해 단순하게 영양섭취나 기호성을 만족하기보다는 식품섭취를 통해 건강을 향상시킬 수 있는 기능성 식품을 선호하게 되었다. 현재까지의 우리나라의 기능성 식품시장은 영세할 뿐 아니라 개발된 기능성 식품의 과학적인 연구들도 또한 미비한 실정이다. Saccharomyces cerevisiea 가수 분해물은 여러 가지 영양성분이 풍부하여 자율신경 조절기능 향상으로 인한 항스트레스와 항피로 및 면역기능 강화 효과가 있으며 불안증 환자와 월경전증후군을 경험한 여성의 증상을 경감시킨다고 알려져 있다.(중략)

인체에 영향을 미치는 진동을 분류하는데 가장 중요한 기준은 주파수이다. ISO의 인체진동관련 규격에서는 인체에 영향을 미치는 거동을 저주파수 운동(0.63Hz이하)과 진동(1~80Hz)으로 나누고 있다［1］. ISO 2631에서는 주파수별로 인체에 미치는 영향을 그림1과 같이 가중치로 정의하여 제시하고 있다. 저주파수 영역의 운동은 외부 거동(주로 수평방향)에 대하여 자세를 유지하기 위해 힘Tm게 되므로 물리적인 피로감을 줄 뿐만 아니라 'Motion sickness'란 증상을 유발한다.(중략)

This study was conducted to identify factors affecting depression in junior nursing students(JNS). The number of the participants was 144 at a college in S and G city. The data were collected using questionnaires about somatic symptoms(SS), sleep quality, stress, adaptation to college life(AC), depression. Mean score of depression was 18.89, 58.3% are experiencing depression that requires clinical treatment. The significant predictors of JNS were levels of depression AC(β=-.503, p=.000) and SS(β=.263, p=.000) respectively, explaining 58.9% of variance. In order to control the depressive symptoms of JNS, it is necessary to diagnose basic learning ability from the beginning of admission and provide guidance management plans to help students adapt to academic activities by providing customized programs for each level to improve learning ability. It is necessary to develop and apply various intervention programs to alleviate physical symptoms such as fatigue/low energy experienced by JNS.

To investigate industrial fatigue and low back pain, the questionaire survey for subjective symptoms of fatigue and low back pain was carried out among 591 male workers aged 20-55 employed in an automobile industry in Korea. Workers participated to this study were divided into low back pain group(LBP) and control group, according to the self-reports by written questionaires. The subjective sysptoms of fatigue comprised three groups of 10 items each, representing dullness and sleepiness(level of cerebral activation), difficulty in concentration(level of motivation) and bodily projection of fatigue. The resultant data were processed for $\chi^2-test$, t-test and a pearson's correlation coefficient to confirm the relationships. The results were as follows: 1. 30 items of fatigue subjective symptoms exeptone item, 'lack in perseverance', were directly associated with low back pain. 2. The percentage of fatigue complaint were sig nificantly higher in LBP group. 3. Of the 30 items of fatigue subjective symptoms, the highest percentage was accounted for 'eye strain'(27.9%), followed by 'whole body feels tired' and 'legs feel heavy'(22.9%), 'feel like lying'(21.4%), 'feel a pain in the low back'(18.7%), 'feel drowsy'(16.4%) and 'feel stiffness in the neck or the shoulders'(16.2%) in the order of sequence. 4. The average weighted score for the first group of fatigue items(dullness and sleepiness) was the largest among three groups and was followed by the second group(difficulty in concentration) and the third group(bodily projection of fatigue) in the order of sequence, suggesting the heavier shift work stress of the workers. 5. In the groups of the aged 30-40, work duration of 5-7yrs, heavy work amount and irregular work speed, significant high fatigue complaints were revealed in terms of eye strain, whole body feels tired, legs feel heavy, feel like lying, feel a pain in the low back and feel stiffness in the neck or the shoulders. 6. A significant negative correlations were shown between age, work duration and eleven subjective symptoms while positive reciprocal correlations were shown between eleven items with one another.
